Major new features of the 3.5 series, compared to 3.4
Python 3.5 is still in development, and 3.5.0a1 is the second alpha release. Many new features are still being planned and written. Among the new major new features and changes in the 3.4 release series so far are
Notes on this release:
- Windows users: if you have previously installed Python 3.5.0a1, you must manually uninstall it before installing Python 3.5.0a2 (issue23612).
- Windows users: If installing Python 3.5.0a2 as a non-privileged user, you may need to escalate to administrator privileges to install an update to your C runtime libraries.
- The OS X installers are now distributed as signed installer package files compatible with the OS X Gatekeeper security feature.
- There are now "web-based" installers for Windows platforms; the installer does not contain Python, but instead downloads just the needed su at installation time.
- The Windows binaries were built with Microsoft Visual Studio 2015, which is not yet officially released. (It's currently offered in "Preview" mode, which is akin to a "beta".) It is our intention to ship Python 3.5 using VS2015, although right now VS2015's final release date is unclear.
- The binaries for AMD64 will also work on processors that implement the Intel 64 architecture. (Also known as the "x64" architecture, and formerly known as both "EM64T" and "x86-64".) They will not work on Intel Itanium Processors (formerly "IA-64").
- There is important information about IDLE, Tkinter, and Tcl/Tk on Mac OS X here.
